当今,网络的使用已日益普及,随之而来的是网络的规模日趋扩大,网络的类型日趋多样化,网络设备日趋复杂,因此管理上维护好网络已经不是一件容易的事。例如,如何诊断和解决网络故障会非常困难,单靠人工已是不可能实现的。另一方面,由于网络的规模越来越大,网络的使用越来越频繁,网络的性能相应地受到很大影响,因此如何提高网络的性能也成为网络系统应用的主要问题。所有这一切,最好的解决办法是通过网络管理的工具来帮助我们完成对网络的
Nowadays, the use of the Internet has become more and more popular. With the increasing scale of the Internet, the diversification of the types of networks and the increasing complexity of the network devices, it is no longer easy to manage the network. For example, how to diagnose and solve network failures can be extremely difficult and impossible to achieve by humans alone. On the other hand, as the network becomes larger and larger, the use of the network is more and more frequent, and the performance of the network is greatly affected accordingly. Therefore, how to improve the performance of the network has also become a major problem in network system applications. The best way to do all this is to use network management tools to help us complete the network
